It is true indeed that long ere the period of which we write the Moorish power in the West had received a severe check, and had, for at least a century, entered on its period of decay. The battle of Tours, fought in 732, had driven the infidels from France. The Christian kingdoms of Spain itself had rallied their courage and their forces, and, in a scene of chivalry, which inspired many a tale and song, had freed at least the northern provinces of that country from the alien power. But weapons of war, as we have already seen in the case of the Arabs themselves, are not the only means of conquest. The surest title of the Moors to glory lies in the prevailing intellectual influence they were able to exert over that Christendom which, in a political sense, they had failed to subdue and dispossess. The scene we have just witnessed in the East was now repeated in Spain, but was repeated in an exactly opposite sense. The mental impulse received from the remains of Greek literature at Bagdad now became in its turn the motive power which not only sufficed to carry these forgotten treasures westward in the course of Moorish conquest, but succeeded, through that nation, in rousing the Latin races to a sense of their excellence, and a generous ambition to become possessed of all the culture and discipline they were capable of yielding. The chief centre of this influence, as it was the chief scene of contact between the two races, naturally lay in Spain. During the ages of Moorish dominion the Christians of this country had lived in peace and prosperity under the generous protection of their foreign rulers. To a considerable extent indeed the Moors and Spaniards amalgamated by intermarriage. The language of the conquerors was familiarly employed by their Spanish subjects, and these frequented in numbers the famous schools of science and literature established by the Moors at Cordova, and in other cities of the kingdom. Proof of all this remains in the public acts of the Castiles, which continued to be written in Arabic as late as the fourteenth century, and were signed by Christian prelates in the same characters;[78] in the present language of Spain which retains so many words of eastern origin; but, above all, in the profound influence, now chiefly engaging our attention, which has left its mark upon almost every branch of our modern science, literature, and art.
